Definitions

  • the invention relates to a device for producing anastomoses according to the preamble of claim 1 and a coagulation electrode according to claim 11.
  • An anastomosis is a connection between two anatomical structures.

  • connection can be made using suture techniques.
  • approaches that allow an organic compound by means of adhesive techniques. Frequently fibrin sealants are used, which allow a very advantageous combination of organs, in particular hollow organs.
  • fibrin sealants are used, which allow a very advantageous combination of organs, in particular hollow organs.
  • compatibility of these adhesives is problematic because they can have thrombogenic and toxic properties.
  • Clamping techniques are also used to connect at a suitable location.
  • Various aids such as rings, cuffs or stents, are used to assist in performing anastomoses.
  • WO 03/061487 A1 It is known to connect hollow organs by the application of a suitable high-frequency current (RF current).

  • the outer sleeve can be opened and put over the inner sleeve and the tissue located thereon.
  • the electrodes are arranged on the sleeves such that the first end and the second end of the vessel are clamped between the electrodes at the sleeves. When the HF current is applied, it flows through the tissue and fuses the ends.
  • a problem of WO 03/061487 A1 is that for welding or coagulation of hollow organs with different diameters, a plurality of differently ausgestalteter instruments are needed.
  • the gap between electrodes and sleeves must be dimensioned such that it is adapted to the diameter of the wall thicknesses.
  • the coagulation process requires a sustained pressing of the tissue structures or vessel end sections throughout the coagulation process.
  • the present invention solves this problem by the device according to claim 1.
  • the object is achieved by a device for producing anastomoses between a first and a second hollow organ, each having an inner and an outer surface, comprising a sleeve with an inner electrode assembly over which the first hollow member is everted so that its inner surface after comes to lie outside, and an outer electrode assembly, which is the inner electrode assembly in particular radially opposite and with the second hollow member, which is pushed over the first hollow member, can be brought into electrical contact, that the electrode assemblies contact outer surfaces of the hollow organs, wherein the outer electrode assembly has a plurality of at least one guide member against each other movable slats comprises, which are designed and movable such that inner edges of the slats in a closed state form a through hole and abut the second hollow organ and in a ⁇ Stammsz a gap leading from the outside to the passage opening is formed between the lamellae, through which the interconnected hollow organs can be led out of the passage opening to the outside.
  • the outer electrode is formed by a plurality of mutually movable blades.
  • the fins are arranged so that they can assume at least two states, a closed state and an open state.
  • the opening state at least the lamellae are spaced apart from the sleeve with the inner electrode arrangement in such a way that a through opening is formed in which the corresponding sections of the hollow organs can be positioned, preferably still with a substantial absence of tissue contact and radial force.
  • the inner edges of the slats are at least partially on the hollow organ and allow direct application of the HF current.
  • the outer electrode arrangement with the lamellae is divisible.
  • a gap can form, which divides the slats. Due to the gap, the unconnected hollow organ or vessel can be introduced or the connected removed from the device.
  • the lamellae can exert a mechanical pressure on the hollow organs.
  • the closing and coagulation conditions can be determined relatively accurately. This can ensure the formation of anastomoses with a high load capacity. After a connection of the hollow organs can be easily removed in the open state, the device. Injury to the organs or excessive loading of the compound produced is avoided.
  • the lamellae can be adjustable in such a way that, in the closed state, an opening is created which corresponds to the hollow organ to be treated.

  • an iris diaphragm is particularly suitable for providing a substantially continuous contact surface of the lamellae.
  • An applied mechanical pressure can be regularly distributed over the outer and surface of the second hollow organ.
  • the sleeve can be arranged fixed relative to the outer electrode in a holder or a holder.
  • the sleeve is in a predetermined position relative to the outer electrode. Positioning the sleeve relative to the outer electrode is thus unnecessary.
  • the device according to the invention can be constructed much more compact by the fixation in a holder. The handling is facilitated by the fixed or adjustable positioning.
  • the holder may be removable for individual handling of the sleeve. That is, the holder can be detached from the device and operate separately from this.
  • the sleeve and device may be coupled such that the sleeve is in an advantageous position relative to the outer electrodes. After this Coagulation process, it may be advantageous to solve the holder back from the device in order not to unnecessarily straining the connected hollow organs.
  • the inner edges of the slats may have a substantially equal distance to the sleeve in the closed state. In the closed state, therefore, the inner edges lie on the second hollow organ, in particular on its inner surface.
  • the HF current is applied directly to the tissue. The connection achieved is correspondingly higher quality.
  • the passage opening can be adjustable in terms of its diameter by moving the slats.
  • the device can thus be opened and closed by moving the slats.

  • the sleeve can be held on an actuating device and designed such that it can be dismantled into two parts such that the parts can also be brought from a closed state to form a closed tubular section into an open state for removal from the hollow organ.
  • the sleeve can therefore be designed in two parts, so that it can be disassembled after or before the application of the HF current. For example, it may be possible to spread apart the individual parts of the sleeve to ensure better handling of the organs. The spreading of the sleeve can also prevent the slipping of the hollow organ which has been slipped over the sleeve.
  • the actuator may be biased in a closed state.
  • the closed state automatically turns on.

  • the clamping device can be adjusted such that the slats are pressed in the closed state with a predefined force against the hollow organs. This force not only allows a safe coagulation of the tissue, but is also sized so that there is no injury to the hollow organs. By adjusting the tensioning device, a repeatability of the treatment results can be ensured.
  • Such a coagulation electrode has similar advantages to those of the device described above.
  • the coagulation electrode is divisible and thus easily removable after the application of the HF current. That is, the coagulation electrode is easily removed from the connected hollow organ.
